The CGI (Common Gateway Interface) defines a way for a web
server to interact with external content-generating programs,
which are often referred to as CGI programs or CGI scripts. It
is a simple way to put dynamic content on
your web site. This document will be an introduction to setting
up CGI on your Apache web server, and getting started writing
CGI programs.

.htaccess files provide a way to make configuration
changes on a per-directory basis. A file, containing one or more
configuration directives, is placed in a particular document directory,
and the directives apply to that directory, and all subdirectories thereof.

HTTP/2 is the evolution of the world's most successful application layer protocol, HTTP.

SSI (Server Side Includes) are directives that are placed in
HTML pages, and evaluated on the server while the pages are

On systems with multiple users, each user can be permitted to have a
web site in their home directory using the UserDir directive. Visitors
to a URL http://example.com/~username/ will get content
out of the home directory of the user "username", out of
the subdirectory specified by the UserDir directive.

Apache httpd has extensive capabilities as a reverse proxy server using the
ProxyPass directive as well as
BalancerMember to create sophisticated
reverse proxying implementations which provide for high-availability, load
balancing and failover, cloud-based clustering and dynamic on-the-fly reconfiguration.
